LOOP-MAKING MACHINE.

SPECIFICATION forming part Of Letters Patent No. 581,580, dated April27, 1897. Application filed March 16, 1896. Serial No. 583,412. (N0model.) Patented in Canada March 5, 1896,11'0. 51,545.

To (tZZ whom it may concern.-

Be it known that I, EDOUARD LEMYRE DIT GAUCHER, a citizen of theDominion of Canada, and a subject of the Queen of Great Britain,residing at Maskinonge, in the county of Maskinonge, in the Province ofQuebec, Canada, have invented certain new and useful Improvements inMachines for Making Loops on Bindingire, (for which I have received apatent in Canada, No. 51,545, bearing date March 5, 1896,) of which thefollowing is a specification.

My invention has reference to a machine for making a loop on the end ofbinding-wires used to bind bales of hay, straw, or other materials; andit consists in two distinct parts, one immovable and having secured toit various camrails, the other movable and having the necessarymechanism to form the loop and cut the wires into suitable lengths, allactuated by means of the cam-rails, &c., placed on the immovable parts,such as described hereinafter.

The object of my invention is to provide a machine to make loops at theends of bindingwires in a substantial and expeditious manner.

Referring to the drawings, similar letters refer to similar partsthroughout the several views.

Figure l is an end view of my machine with certain portions cut away toshow the mechanism. Fig. 2 is a front view. Fig. 3 is a sectional viewthrough line 00 a; in Fig. 1. Fig. 4 is a plan view of the twistingmechanism. Fig. 5 is a front view of the same. Fig. 6 is a sectionalview, through line :0 a," of Fig. 5, of a clamp to hold the wire duringand after being cut. Fig. 7 is a detail view, on a larger scale, of adevice to make the twisting-head rotate one-quarter of a revolution.Fig. 8 is a detail view of the cutter. Fig. 9 is a detail view showingthe method of securing the twistinghook in its head. Fig. 10 is a sideview of two of the cam-rails. Fig. 11 is a view showing the loop beforebeing twisted. Fig. 12 is a view showing the completed loop. Fig. 13 isa side view of a signaling-bell, and Fig. 14: is a top view of same.

My machine consists in the two frames A and B, on which is journaled theshaft 0. To the frame A is firmly secured at d d the panel D, having onits face the endless cam-rail d segmental rails (i and al the segmentalflat rails d" and (1 the segmental rack cl, and the deflecting-wheel 61all joined to it in a suitable way, also the deflecting-arm 61 As forthe movable portion, it consists in the plate E, made out of anysuitable material and mounted on the shaft 0 in a substantial way (shownon the drawings by a disk) and having on its two extremities themechanism shown on Figs. 4 and 5, and also having secured to it thesemicircular guides F. The piece E is cut away at e to show thearrangements of the several parts on its side facing the panel D.

Now to make a loop on the wire all that is necessary to do is to takethe wire from a reel, located at any convenient point and not shown onthe drawings, and then pass it between the guide -wheels G, secured tothe panel D, and pass it over onto the end f of the right-handsemicircular guide F, and there secure its end in any suitable way. Thenby making the piece E, and consequently all that is secured to it, turnon the shaft 0, by means of the driving-pulley c, in the direction H thewire is pulled along and is kept in position by means of thesemicircular guides F. 011 starting the machine from the position shownon Fig. l the hook I, secured into the twisting-head 'L', as shown inFig. 9, that is removable, has its point i turned toward the end ofpanel D, and the one J has its point j turned toward the shaft 0 andbelow the wire K. As the apparatus turns onthe shaft 0 the arm Z of theforked lever L comes in 0011- tact with the segmental cam-rail d andforces the arm 1 against the Wire K, which it holds snugup against thecutter M. At the same moment the outside perpendicular shoe 0, strikingthe segmental rail d tumbles over and makes the twister-head i, andconsequently the hook, turn exactly one quarterturn, this bringing thepoint t" of the hook I in the position shown on Fig. 5that is, aboutperpendicular to the piece E and away from it-by the medium of the shaft0 and gears O and O, the latter being secured and operating thetwister-head 6. After this the arm N of the lever a, coming in contactwith the segmental cam-rail cZ ,is deflected upward from the panel D,and thus secures the wire K between the small projections n on the levera and the ones f on the semicircular guides F and holds it firmly thewhole time the arm N is in contact with the segmental rail d the lever nretaking its position as soon as its arm N passes off the segmental rail(Z by means of the spring 01 As soon, as the wire is secured by thelever n it is severed by the cutter M, which is actuated by its arm mpassing over the rim of the deflecting-Wheel (Z and then retakes itsplace by means of a spring. (Not shown 011 the drawings.) At the sameinstant the free end of the wire is released as the forked lever L,passing off the segmental cam-rail d retakes its normal position bymeans of the spring Z By this time the two trundle-rolls q, secured tothe end of the lever Q, which has its other extremity secured to thepanel D through the arm q, and which run on either side of the endlesscam-rail (:1 as shown in Figs. 1 and 4, come to the deviation d", andthus approach the central shaft 0, this having for effect to pull downtoward the shaft 0 the rack R, secured to the lever at r, and thus makethe hook J, to which the gearj, intermeshing with the rack R,-issecured, turn in the directionj Fi 4, and thus take the free end of thewire K, which has just been cut, with it and bring it in contact withthe split holder j Figs. 4 and 5, where it securely holds it, as shownon Fig. 11. As soon as this is done the gear 0' begins to intermesh withthe segmental rack d, and thus the twister-head 11 and hook I begin toturn in the direction 0", Fig. 5, and as the hook J has folded the wire,or, rather, bent it around the point t" of the hook I, as shown on Fig.11, in forming the'loop S the latter is twisted, as shown at S in Fig.12. As soon as this is done the same operation begins by the mechanismplaced on the other extremity of the piece E, and the wire K beingsevered again the piece so cut falls out with a loop on one of its endsand the operation is continued indefinitely. However, just as it isbeing cut the arm 15 of the lever T comes into contact with the bracket61 and thus forces the end '6 against loop S, just twisted, and runs itoff the point t" of the hook I. The hooks J and I of course retake theirnormal positions by means of the endless cam-rail (Z and gear 0 runningoff the semicircular rack 61 respectively, the teeth in the latter beingso numbered to secure this.

As can be seen, two binding-wires are made at each revolution of themachine.

A worm V, placed on the end of the shaft 0, runs the gear operating thesignaling-bell, which is screwed on the frame B at the points indicatedby b in Fig. 3 and may be so fixed as to ring at every one hundredbinding-wires made. This bell, however, can be dispensed with if notfound necessary.

As the length of the binding-wires vary according to the size of thebales they are to secure, the circular guides F are made with severalholes 20, so that they can be secured to the plate E in such a way as topresent more or less circumference, and thus vary the length of thebinding-wires.
